An in vitro growth system was used to determine the virulence of two samples of Striga gesnerioides from Zakpota in southern Benin. Cowpea variety B301, previously considered resistant to all races of S. gesnerioides, was susceptible to both samples of the parasite. Two other cowpea varieties, 58...

Registration of six improved germplasm lines of cowpea with combined resistance to Striga gesnerioides and Alectra vogelii
The parasitic flowering plants, Striga gesnerioides (wild.) Vatke and Alectra vogelii (Benth.), cause substantial yield reduction in cowpea in the dry savcannas of sub-Saharan Africa. Alectra is more prevalent in the Northern Guinea savanna and Southern Sudan Savanna of West Africa, as well as in...

Breeding cowpea varieties for resistance to multiple strains of Striga gesnerioides
The parasitic weeds Striga gesnerioides (Willd.) Vatke and Alectra vogelli (Benth.) cause considerable demage to cowpea [ Vigna unguiculata (L.) Walp] in the semiarid regions of Africa. Systematic screening has revealed few cowpea varieties to be resistant. Of these, B 301 is resistant to both st...
